Question about Spa Parts Plus GFCI, Circuit Breaker, 30 Amp

30 amp 2 pole GE GFCI breaker pops on hot tub after hrs of use

My 30 amp GE 2 pole GFCI breaker for hot tub keeps popping after hrs of use, usually overnight. Happens when heater on or off. Reading 23 amps on two hot lines. What is the limit on the neutral (volt and amps) when it should pop? I have an amp clamp and volt meter to measure. Do these breakers get weak over time and begin to pop at lower amps? The hot tub is wired correctly and is running correctly when breaker is connected, then pops after hrs of use. Any suggestions or advice on what to check? Would appreciate any advoce/help.

I have seen circuit breakers trip at a lower amperage. It seems that they are weak. Generally circuit breakers run with 80% load with no problem, in your case 24 amps. I would replace the circuit breaker.

Hello shanleys, I have had situations simular to that and have found that the breaker was bad ( weak ) a breaker in working condition should last for years if not a life time of the product, I would check that scense everything else is operating fine. The other would be too much load but it sounds like you have tested that.

I just wired my hot tub into my new house. And GFCI keeps tripping?


Still would go with Miswired.
if this is an auxiliary GFCI Spa Disconnect,
240 VAC, 50 Amp, then...
All of the following needs to be this way:
  • 4 wires from MAIN Circuit panel, into GFCI disconnect box, 2 hots, 1 Neutral, 1 ground
    • 2 hots go onto the disconnects Power Bus Bar for breaker
    • 1 white Nuetral goes to Isolated nuetral bus bar
    • 1 green Ground goes to ground lug directly on the box
  • 1 GFCI in the auxiliary disconnect box
    • The White Pigtail of the GFCI Breaker goes onto the Isolated Nuetral bus bar. There are now two wires there.
  • 4 wires come into box from Spa. (Unless the spa is Specifically a 3 Wire Connection Spa!)
    • 2 Hot/Line wires will go into the L1 & L2 lugs of the breaker respectively.
    • 1 White Nuetral Wire will go into breaker as well at the "Load Nuetral lug, usually marked as 'LN'.
      • It will NOT go on the Isolated Nuetral bus bar.
    • Green Ground wire will be connected to ground lug, 2 wires are now connected there.
  • Connections at spa will be respectively connected: the 2 hots on line 1 and line 2. White wire goes to Nuetralnd green ground will go to a Ground Lug, most likely to metal control box.
If it's not wired in this manner, it is wired WRONG.

My hot tub has been running perfectly until a few nights ago when the GFCI breaker tripped and now it wont reset


Either you have a ground fault or the GFCI is toasted. Turn off the power to the GFCI, open the box the GFCI is in and disconnect the output wires, close up the box, re-energize, and try to reset it again. This will tell you which problem you have.

There is the liquid seeping out of the breakers, it is not water the box is dry and it feels like an oil of some kind. breakers are working and are not hot. i have not seen this before. what is it and what...


It is oil. It's used to extinguish the arc.

When a circuit breaker trips, there is an Arc of electricity made inside the breaker, due to the contacts.
The contacts are instantly brought away from each other.

There are three methods employed to extinguish that arc.

[Extinguish the arc. Non-technical explanation. With out some medium to extinguish the arc produced inside, it would go Z-z-z-z-z-z-z-z-z-z-z-z-zap, instead of z-zap]

Oil, Air, and Sulfur Hexafluoride.

So yes, as long as the circuit breaker doesn't have to trip, and produce the arc inside, it is a working circuit breaker.

Is it a safe unit?

NO

The method employed to extinguish the arc if the breaker trips is leaking out.

Replace all breakers that are doing this.

Average cost for a GE single-pole 15, or 20 Amp is around $11 here. A few dollars more for 30 and 40 Amp, but usually double-pole breakers are used for 30, and 40 Amp.

40 amp gfi on hot tub keeps tripping.I have a 50 amp.can I use?


Your hot tub needs GFI protection because it is electrical, and people sit inside water that could be exposed to electric current.
You have a fault to ground that needs to be fixed.

Size 8 wire for 50Amp breaker.
Size 6 if tub is 50-100' feet away

My breaker is conected to a hot tub. tub was working fine in auto mode. Turned on jets and breaker tripped. will not reset can you help me


I am assuming this is a GFCI circuit breaker? If it is it will have a "test" button on the breaker. When you say "jets" i'm assuming you mean when you turn on the blower to make the air bubbles? It could be you have a problem with the blower motor. When you start the blower, it trips the breaker. Be sure the blower is in off position when you reset the breaker. The most common fault though on a spa/hot tub is with the heater. If the element goes bad, and current flows to ground, it will trip the GFCI breaker. Again try and turn all functions off. Reset breaker, and then turn on one at a time till the breaker trips. First the pump, then the heat, then the blower.

The 20 amp breaker for our spa circulation trips within hours or as long as one week. Tthe breaker does not trip off but cuts the power. it requires tripping it off then turning back on. Is this a faulty...


This is probably not a faulty breaker. A GFCI breaker is designed to trip when there is a 4-6ma inbalance of current(usually 5) between the two current carrying conductors (hot and nuetral) You may be having a moisture problem. Check all of your electrical connections (with power off) for moisture. If you find any throughly dry (like with hair dryer) and seal to prevent further problems. Your motor may be an open drip proof motor. IF condensation builds inside that coud also cause problem. There are GFCI testers available if you wanted to test your breaker, but for one time it probably isn't practical.

When Working with Household Electricity you want to always keep in mind that the BLACK wire ALWAYS carries DEATH. What I mean by this is that working with a Single Phase Circuit (one that uses 120VAC) the only wire that should be carrying a voltage is the BLACK one, the other 2 wires (typically the White Neutral and Green Ground) should both be electrically connected to Earth Ground (usually by being attached to your water pipe.)

It is also possible that your hot tub may use more than 20 Amps.

Hooking up a Hot tub


Everything above tells me this is 120V unit...if thats the case a single pole breaker is sufficient. Also by what you have written, a 15 amp breaker should suffice.

Gfci breaker for spa


gfci's are designed to trip if they receive voltage on there ground/neutral side, therefore my vote is for Smithbrother I would say there is probably a partial short somewhere in you system.
